With a single tool there is no possibility of misselection or overlapping purpose. Its intent (fetch server capabilities/rate card before sending) is unambiguous.
The lone name refueler_capabilities is snake_case and namespaced, which is readable and predictable. It is noun-based rather than a verb_noun action pattern, but consistency cannot really be violated with one tool.
A single tool is far too thin for a server whose description implies a send workflow. There is no operation to actually do anything, making the surface feel like a stub.
The tool explicitly exists as a precondition for 'any send', yet no send, quote, status, or account operation is exposed. The advertised domain is essentially uncovered, leaving agents at a dead end.
